Said blcck and consequently as thc scrivici 1 2r the block against scparaticii from tlm of? the tripper plate the machine indicated by the reference character p and being here illustrated as three in number. rFhe pins are designed for cooperation With the trip device hereto-fore mentioned, which trip device includes brackets Z secured by screws n to the upper side of the frame a and a plate which is provided at its ends with ears pivotally mounted as at m upon the said brackets. Upon one 'face and at its opposite ends, the plate e' is provided with tripping fingers g having stepped shoulders for the successive coperatiou therewith of the pins p. By reference to Figs. G andA 7 of the drawings it will be observed-that the tripper plate fi may be swung upon the pivots m to assume the position. shown :in Fig. 6, .in which position the machine is adapted for the honing of a razor blade, or to assume the position. shown in Fig. 7, in which position is adapted tor the strcp'ping oi" a razor blade. ln the first instance, that is to say in honing the blade, the blade is 'aoved edge iirst over the surface of the hone and is automatically re versed at the end of each stroke of the carrier block, and in the second instance, or, in other words,- in stropping the blade, the blade is caused to move bach first over the stropping surface and is automatically re versed at the end -T each stroke of the carrier block.

The reference letter o indicates the blade holder into which the 'razor blade o is inserted and this holder is provided 'with a stem which is fitted into the shaft f and i's provided with a notched end u which straddles one of the pins p which pin at its inner end extends into the hollow shaft. ln this manner the stem of the bolderis connected tor rotation with the shaft and yet the stem may he readily withdrawn from the shaft when desired.. Fixed upon the stem of the holder is a cam the outline oi? which is clearly shown in Fig. 2 of the drawings and this cam is designed to ride beneath a presser plate w which is provided at each end with an opstanding rod or stem is which tits slidably through the bore of a sleeve nut e adjustably 'threaded through a bridge member i secured by means of screws a upon the base of the machine. Springs as are mounted upon the stems 7c and bear at their lower ends upon the upper side of the presser late and at their up er ends against the lbvver ends of the said s, eeve nuts, and it will be understood that while the plate may move upwardly against the tension of the springs, the stems 7c havel free sliding movement through the respective nuts, andthe tension of the springs w may be varied by' adjusting the said nuts so that the presser plate may be caused to bear more or less firmly upon the cam t. At their upper ends, the stems k project through guard members y secured upon thel bridge member j and one end of of the machine is as follows: A hone 1 4first placed in the recess in 70 the base of the machlne and the tripper device is adjusted to the position shown in Fig. 6, after which the razor blade is fitted into the blade holder and the holder is inserted into the hollow shaft f. The handled is then grasped and the carrier block is reclprocated lengthwise ci the machine. At the end ot each strokeI of the block the shaft is reversely rotated to approximately a half turn and the razor blade holder is correspondingly turned so or reversed, this reversal being accomplished through the successive engagement of the pins p with the stepped shoulders of the trip fingers. In the reciprocatory motion of the carrier bloclr the shoulders h will coact with the guido e to 'cause reciprocatory motion of the shalt through the said carrier block a and consequently the razor blade will be moved not only longitudinally of the hone but also across the said hone laterally. The

razor blade is held in contact with the sur face of the lione through the downward pressure exerted by the presser plate eu upon the cam t and this pressure may be regulated by adjusting the sleeve nuts a( In adapting the machine for use in stropping a razor blade, a strop is substituted-for the hone and the razor blade holder is withlrawn, reversed, and then reassembled with the shaft f, the tripper device being also re- 10G versed Vso as to assume the position shown in Fig. 7 of the drawings.

Having thus described the invention, what is claimed as new is:

l.. In a machine of the class described, a

support, an abradingelement mounted there on, a member mounted u pon the support for reciprocation beside the said element, Va shaft mounted upon the said member, a

blade holder carried by the shaft, a series of pins carried by the shaft and radiating therefrom and relatively displaced, and spaced trip members having stepped shouL ders for engagement by the said pins at the ends of the strokes of the said 'member 115 whereby to impart rotarylmotion to the blade holder at the termination of each stroke.

2. In a machine of the class described, a

support, a member mounted upon the support for reci procation, a shaft rotatably andl slidably mounted upon the member, meanso for imparting sliding motion to the shaft" upon -reeiprocution of the said member,

spaced tripping members each having ase- '125 ries of tripping shoulders arrangedl in stepped relation, he said tripping members being arranged in the path of movement of the shaft when the first-mentioned member is reciprocated, al blade @www holder Carried by the shaft, end radial pins the shaft at the ende of the srkee of the reimentcmed member."
